The Duc might not have dominated at the drag strip - with that self-servo clutch it must be a nightmare to launch - but it certainly killed 'em in 60-80mph top-gear roll-ons, tall gearing notwithstanding, acc to those Cycle World specs (bottom of linked page). That motor really kicks.

You've not expressed any interest in the Guzzis. Do these not grab you?

I suppose, with the weight and that 32 Litre tank, they are too much on the touring side. Guzzi character and that fuel range appeals to me, tho.
